Example of an intrinsic colloid is

Options

A. `As_(2)S_(3)` sol
B. S sol
C. Egg albumin
D. `Fe(OH)_(3)` sol

Answer

To solve the question regarding an example of an intrinsic colloid, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Colloids**:
- Colloids are mixtures where one substance is dispersed evenly throughout another. They consist of two phases: the dispersed phase (particles) and the dispersion medium (liquid or gas).

2. **Types of Colloids**:
- Colloids can be classified into two main categories:
- **Lyophilic Colloids (Intrinsic Colloids)**: These are colloids where the dispersed phase has a strong affinity for the dispersion medium. They are stable and can be easily formed.
- **Lyophobic Colloids**: These are colloids where the dispersed phase has little to no affinity for the dispersion medium. They are less stable and require special methods for formation.

3. **Identifying the Options**:
- The given options are:
- A) As2S3 (Arsenic trisulfide)
- B) Sulphur salt
- C) Aluminum ferric hydroxide salt
- D) Egg albumin

4. **Analyzing the Options**:
- **As2S3**: This is a lyophobic colloid as it does not have a strong affinity for the dispersion medium.
- **Sulphur salt**: This is also a lyophobic colloid.
- **Aluminum ferric hydroxide salt**: This is typically a lyophobic colloid as well.
- **Egg albumin**: This is a protein that has a strong affinity for water (the dispersion medium), making it a lyophilic colloid.

5. **Conclusion**:
- Based on the analysis, the correct answer is **D) Egg albumin**, which is an example of an intrinsic colloid.

### Final Answer:
The example of an intrinsic colloid is **Egg albumin**.
